Yes, I took it down after finding the scanners had stopped receiving the system reliably for an unknown reason. Not sure what the problem is .. I'm going to try and look at it soon to see if I can figure out what happened, but don't have any ideas at the moment.
Yeah, I was a little annoyed with myself when I figured it out - the signal bars were jumping around so it looked it was receiving something, otherwise I might have gone down that road sooner, but it fooled me into thinking the signal was still there but weaker. Must've been picking up some other distant system, or I noticed there's some sort of very regular data burst on another listed CC that doesn't sound like any trunking standard I've heard before, and maybe that's what it was hearing? Not sure.
